two equal roots
, then find the value of
'\(t\)'.
1
.
\(x^2 + tx + 9 = 0\)
\(t = \sqrt{6}\) or \(t = -\sqrt{6}\)
\(t = 16\) or \(t = -16\)
\(t = 6\) or \(t = -6\)
\(t = 4\) or \(t = -4\)
2
.
\(16x^2 + tx + 9 = 0\)
\(t = 24\) or \(t = -24\)
\(t = 576\) or \(t = -576\)
\(t = 16\) or \(t = -16\)
\(t = 12\) or \(t = -12\)
